Biological Activity

[Description]:

A-286982 is a potent and allosteric LFA-1/ICAM-1 interaction inhibitor with IC50s of 44 nM and 35 nM in an LFA-1/ICAM-1 binding and LFA-1-mediated cellular adhesion assay, respectively[1][2].

[Target]

IC50: 44 nM (LFA-1/ICAM-1 interaction in an LFA-1/ICAM-1 binding assay) and 35 nM (LFA-1/ICAM-1 interaction in LFA-1-mediated cellular adhesion assay)[1]

[In Vitro]

A-286982 binds to the I domain allosteric site (IDAS). The allosteric ICAM inhibition such as this would be expected to exhibit the unsurmountable competition we have observed for A-286982 as a result of the passage of this allostery through the A-286982 binding site in its transmission from the β subunit I-like domain to the α subunit ICAM binding site[2].
